GEORGE W. GWINN, OF BROOKLYN, NEW YORK, ASSIGNOR TO AUTOMATIC PACKING & LABELING COMPANY, OF DURHAM, NORTH CAROLINA, A CORPORATION OF NORTH CAROLINA.

PASTING DEVICE FOR LABELING-MACHINES.

To all whom it may concern Be it known that I, Gnoncn W. GWINN, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Pasting Devices for Labeling-Machines, of which the following is a specification.

This invention relates to an improvement in pasting mechanism for labeling machines.

In my Patent No. 1058579, patented April 8, 1913, machine for packaging materials, there is disclosed a device for pasting a revenue stamp upon a package. The present invention is an improvement over the pasting mechanism of the patent above referred to and is designed to be used in place thereof upon the same and similar packaging machines.

The invention consists in certain combinations and constructions which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the .accompanying drawings, which form a part of this specification and in which like characters of reference indicate the same or like parts, Figure 1 is a plan view of a device constructed in accordance with the invention. Fig. 2 is a side elevation of the structure shown in Fig. 1. And Fig. 3 is an end elevation of thesame structure, partly broken away.

Referring to the drawings, 1 indicates d agrammatically a stamp magazine in which revenue stamps are stored in a pile, with the lowermost stamp protruding at 2 from the magazine. This magazine and themechanism for causing the lowermost stamp of the pile within the magazine to protrude are fully disclosed in the patent above referred to and a detailed description thereof is omitted herefrom in the interest of brevity and clearness. Suitably supported fromthe main frame of the machine in connection with which the present invention is used is a paste receptacle 3 adjacent the protruding end of the lowermost stamp at 2. Mounted within the paste receptacle 3 is a paste ap- Patented June 6, 1916.

plying wheel 4:, the operating periphery of which is somewhat narrower than the revenue stamp to which paste is to be applied. Th1s paste applying wheel is mounted upon a short shaft 5 journaled in suitable bearlngs 6 and 7 formed in the paste receptacle. Within the paste receptacle 3, the short shaft 5 carries a gear 8 which is in mesh with a gear 9 wholly submerged in the paste receptacle and carried upon a shaft 10. This shaft 10 also carries a paste feed wheel 11 running submerged in the paste and adapted to supply paste to the operating surface'of the paste applying wheel 4:. A doctor 12 is provided for the purpose of scraping excess paste from the paste applying wheel 4: and also from the gear 8. It may be here remarked that the pasteused in the device is of such character that it does not clog the gears 8 and 9 submerged therein.

Upon the outer end of the shaft 5 is a gear 13, this gear being in mesh with a gear 14 mounted upon a short shaft 15, which shaft is journaled in a boss 16 formed upon an upright 17 rising from theframe of the machine in connection with which the device is used. Upon the shaft 15 is loosely mounted a gearlS and beyond this gear a ratchet 19 is fixed upon the shaft 15. This ratchet is engaged by a pawl 20 carried upon a disk 21 secured to the gear 18. A- spring 22 serves to keep the pawl and ratchet in proper correlation. The gear 18 is in mesh with a gear 23 loosely mounted upon a stud 24, the stud being held in position in the upright 17 by means of a set screw 25. The gear 23 is engaged by a rack 26 one end of which is secured, by means of a set screw 27, in a bracket 28. This bracket is mounted to slide to and fro upon a bar 29 suitably supported on the main frame of the machine in connection with which the device is used. The

bracket 28 has depending therefrom a lug '30 to which suitable means is attached for direction which is the direction in which it moves while drawing a stamp across the periphery of the paste applying wheel.

Secured to the bracket 28 is a twopronged fork 31-32, the two prongs being connected with a tail 33 which is held to the bracket 28 by means of screws 34-. Journaled in the bracket above this fork is a shaft 35 and upon this shaft is mounted an arm 36 carrying at its extreme end two jaws 37 and 38 which respectively cooperate with the prongs 31-32 to form two pairs of gripper jaws spaced apart and adapted to pass one on either side of the paste applying wheel 4 in order to reach and seize the opposite edges of the lowermost stamp of the magazine protruding from said magazine at 2.

For the purpose of causing the gripper aws to close at one end of the movement of the bracket 28 and to open at the other end of the movement, there is provided a trip mechanism in part carried by the bracket and in part carried by the bar 29. This trip mechanism consists of the following parts: Mounted upon the front end of the shaft 35 is an arm 39 and adjacent this arm is mounted a trip lever 40 fulcrumed on a screw 40 which is threaded in the bracket 28. A detent 4 1 is secured to the arm 39 by means of screws 42 and this detent is normally engaged by the trip lever 40, as shown in Fig. 2. A spring 43 is provided for holding the upper end of the trip lever 40 in engagement with the arm 39,and a spring at is provided for causing the arm 39 to rock the shaft 35 and thereby close the gripping jaws whenever this is permitted by the operation of the trip lever 40. In the drawings the parts are shown in the position in which they lie when a stamp has been drawn across the paste applying wheel to delivery position and the gripping jaws have been opened. lhe opening of the jaws is effected by the contact of the lower end of the lever 39' with an adjustable abutment 45 secured to the bar 29 by means of screws 46. A similar adjustable abutment 4'7 is secured to the bar 29 by means of screws 48, the abutment 47 being so located that the lower end of the trip lever 40 comes in contact with it as the bracket 28 reaches the end of its movement toward the stamp magazine 1. 49 is provided on the shaft 35 for the purpose of cooperating with the arm 39 to prevent longitudinal movement of the shaft 35 in its bearing. 7

In view of the foregoing, a detailed description of the operation ofthe device is deemed unnecessary and is therefore omitted in the interest of brevity.

What is claimed is: a
